@DreamCaster you gotta relog before .home or .loot work
I suggest you do .loot grade blue
and then .loot set grade
then .loot set selected_item
This will set the loot filter to use the grade AND selected item filter, and the grade will be blue or above, UNLESS the selected item is present.
then you can add 3 item id with .loot add ****
and you can remove them with .loot remove ****
I add the forbidden books and the trash loot usually. This lets me farm very fast.
Ancient Spirit Dust: 721002
Helms Trash: 44179
Forbidden Book: 40220
With these 3 selected_items AND loot grade blue, you will be able to farm helms cave for HOURS and not have to touch inventory. TO CLARIFY A SHORTENED VERSION IS BELOW:
.loot set grade
.loot grade blue
.loot set selected_item
.loot add 721002
.loot add 44179
.loot add 40220
Use .loot info to make sure the filter has the above settings (for helms cave atleast) and ajust where necessary. I usually swap the forbidden book out and the helm fragment if im grinding somewhere else, but i have all of the ITEM ID written in a notepad next to me for quick ez loot filter change.
I know this wasnt the response you wanted in regards to actually ENABLING the loot filter, but i thought id take the opportunity to share some of the stuff ive learned.
